A ketone test checks for ketones in your blood or urine. Ketones are substances that are made when the body breaks down fat for energy. Normally, your body gets the energy it needs from carbohydrate in your diet. But stored fat is broken down and ketones are made if your diet does not contain enough carbohydrate to supply the body with sugar (glucose) for energy or if your body can't use blood sugar (glucose) properly. Ketones can be tested in a laboratory.
Note: Fallingwater. (not Falling Water) Fallingwater, the house designed by American architect Frank Lloyd Wright for Edgar Kaufmann in southwestern Pennsylvania, hangs over a waterfall using the architectural device known as the cantilever.
The city of Chicago is known for many things. It is known as The Windy City more for its politics than for its weather. It is well known as the home for many of the works of architect Frank Lloyd Wright. It is the home of the Merchandise Mart which is the only building in Chicago (and maybe the country) that has its own zip code (60654). It is known as the home of one of the tallest skyscrapers in the world, the Sears Tower (or, as some now call it, the Willis Tower). It is known for the Great Chicago Fire which is fabled to have been started by a cow kicking over a kerosene lantern, but which became the civic lesson from which many current city ordinances were enacted.
